Wavefront LASIK – A custom LASIK

Wavefront LASIK , is the latest technology in the vision correction industry .
This technology has taken the LASIK eye surgery a further step . where it uses a laser to create a cornea flap(the INTRALASIK procedure), and a Custom Wavefront technology to guide the excimer laser for the best possible results in the second step of the LASIK procedure.
With this technology the LASIK surgery became safer and more precise , and that's why it's being called the Custom LASIK
As we know , everyone's eyes are not the same …, and with the advanced software called Wavefront, the doctor get's the ability to get a 3-dismensional measurements of the patient's eye , and as a result of these measurements a customized map of the patient eye is obtained, this map shows how the patient 's eye process images when light enters. And therefore a customized surgical plan is taken to correct the irregularities . The correction is determined precisely at specified depth and position according to the measurements obtained, With these measurements, the doctor could use a laser to reshape the cornea properly.
This accuracy helps in the quality of the patient postoperative vision , and this is what is called wavefront LASIK or custom LASIK.

Femtosecond Laser

What is a Femtosecond Laser?

A femtosecond laser is a laser which emits light pulses with a duration measured by a unit called a "femtosecond ". One femtosecond is equal to one millionth of one billionth of a second, or one millionth of a nanosecond.
The femtosecond laser emits ultra-short infrared light to a precise depth within the interior of the cornea . creating microscopic bubbles of carbon dioxide and water at their point of impact. This means photodisruption "the process name" only occurs in the focal point while tissue outside the defined area remains untouched. A complete cut in a level is achieved by placing thousands of laser pulses next to each other. Then the cornea flap is lifted up with a precision instrument.


INTRALASIK , Also know as INTRALASE , Bladeless LASIK and All –Laser-LASIK is the alternative to the Microkeratome in the traditional LASIK procedure . It is a predictable method for creating the corneal flap than the conventional mechanical microkeratome laser.
As it's well known , the LASIK eye surgery in general consists of two steps:
1. creating a flap on the cornea's outermost layer, called the epithelium.
2. Reshaping the cornea by excimer laser.
In the traditional LASIK procedure , the Microkeratome (a metal blade ) is being used to create the flap ,where in the IANTRALASE or INTRALASIK procedure the patient can undergo a bladeless form of LASIK ,where a femtosecond laser is used to create the flap during the LASIK eye surgery . therefore the patient is provided with a "fearless" vision correction surgery with higher level of safety and accuracy……why??!!....
In the Intralase procedure , we get rid off those Postoperative complications associated with the use of the microkeratome in the traditional LASIK procedure here comes the safety, and…because the Intralase uses a computer controlled laser that delivers pulses of femtosecond laser light to the cornea ..this results in a greater accuracy in flap size, shape, and thickness.
